Product Description

 Description: HJ107 is a fused type no manganese-oxide flux with pumiceous granule of bluish gray to dark gray color, about 10-60 mesh in size. This flux is designed for welding of austenitic stainless steel and is of characteristics with less carbon increment and less chromium loss.

Application: This flux is recommended to use with H0Cr21Ni10, H0Cr20Ni10Ti, H00Cr24Ni12Nb,H00Cr21Ni10Nb, H00Cr26Ni12 and H00Cr2Ni10 wires and strips, welding of stainless steel and anti-corrosion cladding of nuclear pressure vessels and petrol chemical installations. It is also used for repair welding of high manganese steel with H0Cr16Mn16 wires.

For welding of niobium stabilized stainless steel, the flux of HJ107Nb may be selected to solve the problem of difficult removal of welding slag.

Guidelines For Usage:

1.Dry the flux at 250°C for 2 hours before use.

2.Completely remove rust, oil and dirt from the groove surface prior to welding.
